' UNITED STATES PATENT OFFICE.

JOHN J. SOHRAG, OF MOUNDRIDGE, KANSAS.

To all whom it may concern:

Be it known that 1, JOHN J. SoHnAG, a citizen of the United States,residing at Moundridge, in the State of Kansas, have invented a new anduseful Improvement in Stackers, of which the following is aspecification.

My invention is an apparatus especially adapted for stacking headedwheat and other grain in high and large stacks.

The object of my invention is to provide a stacker capable of handlingheaded wheat and other headed grain. And it consists of the parts,improvements, and combinations herein described and claimed.

In the drawings accompanying and forming part of this specification andin the description of the drawings, I have shown my invention in itspreferred form, and have shown what I deem to be the best mode ofapplying the principles; but obvious changes in detail, form,proportions, and arrangement, and the transposition of parts andsubstitution of equivalent members, may be resorted to, within the scopeof the appended claims, without departing from the spirit of theinvention.

Figure 1 is a side elevation of a stacker for headed wheat, made inaccordance with the principles of my invention, the carrier and otherparts being shown in position with the carrier down, or on the ground,ready to receive a load; and in a dotted outline I have shown thecarrier elevated to such a position that the cable-lifter has beenreleased and the rope connectin same with the carrier support slightlyrelaxed. Fig. 2 is a plan view, certain parts of the floor of thecarrier and of the carrier frame being removed to disclose the manner ofconnecting the parts thereunder.

Similar reference characters indicate like or corresponding partsthroughout the two views.

I provide a suitable frame, preferably of about the shape shown in thedrawings. The base consists of two long beams 1, 1, at one end of whichis a cross-bar 2, while suitable braces 3, 3, 4 may also be provided tohold the beams in proper relative position. At the other end, a block 5is fastened to the under side of each beam, and through the blocksextends a shaft or axle 6 on which are mounted the wheels 7, 7 whichsupport that end of the apparatus, the other end rest- 1 Specificationof Letters Patent.

ing on the ground. At the end of each beam is an upright or stud 9,forming the end of the frame, and a diagonal guide and brace 10 extendsfrom each beam, to the corresponding stud 9, one on each side of theframe. The studs and braces are connected at the top by a cross-bar 11.

12, 12 are short braces extending between the base beams and thediagonal guides and braces 10, and 13 is a cross-bar extendingthereacross.

14, 14: are additional short braces extending between the base beams andthe studs and supporting a shaft 15 on which is mounted a compound powerdrum consisting of a large cent-rally disposed drum l7, and two smallerdrums 16, 16 at the sides thereof. The cable 18 is wound around thelarge drum and is provided with a hook 19 so that the horses may bequickly hitched thereto to pull said cable and unwind it from the drum.A cable 20 is provided for each of the smaller drums to carry the load;so that it is clear that when the horses pull the cable 18, the cables20, 20 will be wound up on the smaller drums, the power applied beingincreased according to the relative sizes of the drums. Arrangedalongside of each side of the frame is another beam 21, which is pivotedto the axle 6 at one of its ends. In the other end of these two pivotedbeams is a rod 22, on which is mounted the carrier comprising thecrossbeams 23, 23, the end pieces, 24-, 21, the floor 25, and the side26. This carrier may be of any suitable size. I prefer to make it of asize sufficient to hold the capacity of the header-box which isdischarged into the carrier over the side 20. The carrier is so disposedon the pivot rod 22 that the heavier weight, both when loaded and whenun loaded, is in the rear, or on the left-hand (viewed in the drawings)side of the pivot, so that its natural tendency is to tilt backward. Oneend of a rope 27 (there being one such rope on each side of the machine)is secured to the forward end of the carrier, and from there the ropepasses over the pulleys 2S and 29, which are secured to the beams 21,and to the shaft 30 which is mounted on the studs 9, 9. The other endsof the ropes are secured to this shaft as indicated in the drawings. Theshaft is I provided with a crank and handle 31 to wind and unwind theropes thereon, and

also with a ratchet and pawl 32 to hold the the beams 21, 21, theshortening of the distance between 29 and 30 will permit the rope toplay out correspondingly between 28 and the carrier, the result beingthat the carrier will be kept in approximately level position at allpoints of its travel. At each side of the frame is a beam 34: pivoted onthe basebeam 1 at '33. These two beams are secured together by braces35, and at the top is a cross-bar 36. These elements constitute thecable-lifter as will be explained presently. Secured to the cross-bar 11are two pulleys, one for each cable 20, from which the cable extends,when the carrier is down, over the cable lifter and thence down to thecarriersupporting beams 21, to which the ends of their respective cablesare secured. The braces 10, 10 are so arranged as to form guides for thebeams 21, 21 of the carriersupporting frame as said carrier is liftedfrom lower to upper position. Stop-blocks 4'0, 40 are secured to thesides of the braces l0, 10 to stop the carrier, and these blocks may beadjusted by means of the bolts. 4:1 and a series of holes 42, so thatthe said beams 21, 21, may have a shorter or longer travel, as may bedesired. The cable-lifter frame iscomiected to the carrier-supportingframe by means of a couple of cords 37, 37.

To operate my apparatus, it being normally in the position shown in thedrawings, and supposing the carrier to be loaded: The horses are hitchedto the hook l9 and pull the cable 18, unwinding it from the drum 17,thereby winding up the cables 20, 20 on the smaller drums. Obviously adirect pull from the pulleys 38 on the carrier-supporting frame would bea very severe strain and would be impracticable for lifting a heavyload. To give more of an upward pull, the cable-lifter is provided,whereby, as indicated in the drawings, the pull on thecarrier-supporting frame is upward. As the cables are thus pulled, thecarrier is raised, being in a level position at all points ashereinbefore described, and the cable-lifter is carried with the cablesuntil it strikes against the cross-bar 11, when it is slightly below thecables and out of contact there-' out, the forward end of the carriercoming down against the upper ends of the braces 10, 10. To return thecarrier, it may be first let back to its level position by releasing thepawl and ratchet and unwinding the guideropes,- and the carrier may bepulled back by a rope or cord fastened to the shaft 22 or by any othermeans. hen the slack in the cords 87 is taken up, the returning carrierwill also pull back the cable-lifter with the cables thereon the normalposition of the cable-lifter being resting against the crossbar 13, asindicated. To throw the contents of the carrier fart-her over on thestack, the.

blocks l0 may be set farther along on the braces 10, and by extendingtheends of the blocks beyond the ends of the braces, the forward end ofthe discharging carrier will not come down so far and will throw thegrain still farther forward.

The apparatus may be hauled or pushed about short distances on thewheels 7 7, by applying the power at the opposite end; but fortransporting longer distances, a removable wheel or wheels may beprovided for that end as well. 7
